Question

Question 1

Determine the midpoint of the segment with endpoint (-9,3) and (7,-8).
Question 2

Answer 1

m (-1, -2.5)

Explanation:

x1=-9 x2=7 y1= 3 y2=-8

-9+ 7 3+ -8

m= ------------ , -----------

2 2

m= -2/2, -5/2

m (-1, -2.5)

Answer 2

(-1, -2.5)

Explanation:

the midpoint of a segment is
`((x1+x2)/(2) ,(y1+y2)/(2)`
`)`, given points (x1, y1) and (x2, y2)

`midpoint=((-9+7)/(2), (3-8)/(2) )`
`= ((-2)/(2), (-5)/(2) ) = (-1, -2.5)`
